A story in PCL Link Dump this week discussed one of the strangest events in music and baseball history - the "anti-disco" riot at Comiskey Park in Chicago. on July 12, 1979. Steve Dahl, a Chicago DJ on WLUP, arranged for a promotion, "Disco Demolition Night" in which fans were to bring their unwanted disco records to that nights double header between the Chicago White Sox and the Detroit Tigers. In return, they would be admitted for 98 cents. The expected crowd was 12,000 but 90,000 showed up. Comiskey Park could only seat 52,000.
Between the games, a pile of disco records was blown up on the field and soon an out of control disturbance developed. The White Sox ended up forfeiting the second game of the double header. This event is cited as the end of the disco era by some, but that's quite a bit overstated.
